i have a thermacare heat wrap that i'd love to use on my back when i sleep. i sleep on my stomach so the "no extra pressure" issue is covered, but i was wondering what on earth happens after the first 8 hours? does your skin explode?
should i just set a timer on my phone for 8 hours so i won't die? if i do though, i won't get to sleep as much as i'd like to. :(
